OverviewThe ATmega8A is a low-power CMOS 8-bit microcontroller based on the *R RISC architecture.By executing powerful instructions in a single clock cycle, the ATmega8A achievesthroughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumptionversus processing speed. The *R core combines a rich instruction set with 32 general purpose working registers. All the32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independentregisters to be accessed in one single instruction executed in one clock cycle. The resultingarchitecture is more code efficient while achieving throughputs up to ten times faster than conventionalCISC microcontrollers.The ATmega8A provides the following features: 8K bytes of In-System Programmable Flashwith Read-While-Write capabilities, 512 bytes of EEPROM, 1K byte of SRAM, 23 general purposeI/O lines, 32 general purpose working registers, three flexible Timer/Counters withcompare modes, internal and external interrupts, a serial programmable USART, a byte orientedTwo-wire Serial Interface, a 6-channel ADC (eight channels in TQFP and QFN/MLF packages)with 10-bit accuracy, a programmable Watchdog Timer with Internal Oscillator, an SPI serialport, and five software selectable power saving modes. The Idle mode s*s the CPU whileallowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning. ThePower-down mode saves the register contents but freezes the Oscillator, disabling all other chipfunctions until the next Interrupt or Hardware Reset. In Power-save mode, the asynchronoustimer continues to run, allowing the user to maintain a timer base while the rest of the device issleeping. The ADC Noise Reduction mode s*s the CPU and all I/O modules except asynchronoustimer and ADC, to minimize switching noise during ADC conversions. In Standby mode,the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allowsvery fast start-up combined with low-power consumption.The device is manufactured using Atmel’s high density non-volatile memory technology. TheFlash Program memory can be reprogrammed In-System through an SPI serial interface, by aconventional non-volatile memory programmer, or by an On-chip boot program running on the*R core. The boot program can use any interface to download the application program in theApplication Flash memory. Software in the Boot Flash Section will continue to run while theApplication Flash Section is updated, providing true Read-While-Write operation. By combiningan 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the AtmelATmega8A is a powerful microcontroller that provides a highly-flexible and cost-effective solutionto many embedded control applications.The ATmega8A *R is supported with a full suite of program and system development tools,including C compilers, macro *emblers, program de*/simulators, In-Circuit Emulators,and evaluation kits. 本公司是一家*销售半导体电子元器件的电子分销商。主要经营*元器件。东芝光耦TOSHIBA,安森美ON，意法半导体ST,恩智浦NXP,国际整流IR,德州仪器TI等。为了能更加方便顾客买到*原装产品，公司常备大量现货库存,我们采取的是以诚取胜的销售策略,不但为顾客*了宝贵的时间，而且*了工作效率。我们奉行的是真诚守信,微利多销的经营宗旨.我们*坚持以客户为中心,对于*的追求将永无止境,而对于客户的服务也将是我们长期坚持不懈并照例*的工作之一.不论在何时何地本公司将会以崭新的面貌，和更加饱满的热情服务于支持和关心我们的客户。热情欢迎广大客户来人、来电咨询与采购！ 诚信合作--共赢未来 TOSHIBA光耦系列：TLP521 TLP621 TLP627 TLP250 TLP550 TLP181 TLP121 TLP127 TLP 113 TLP785 TLP781 TLP185 TLP421 FAIRCHILD光耦系列:MOC3021 MOC3041 MOC3063 MOC3083 MOC8050 4N25 4N35 6N137<安华高》6N136 NEC光耦系列：PS2501 PS2505 CNY17 SHARP光耦系列：PC817 PC929 PC942 NXP单片机集成电路系列：LPC2000 LPC1700 LPC1300 LPC1100 LPC900 LPC700 ，74HC系列 ATMEL单片集成电路系列：ATMEGA8A,16A,32A,64A系列 AT89C51/52/55WD,AT89C2051，AT89*051，ATTINY13/2313， ATMEGA48/88系列，AT24C02/04/08/16/32/64/128/256/512/1024 MICROCHIP单片集成电路系列：PIC16F,PIC12F，PIC16C,PIC18F, ON电源集成电路：UC38系列，NCP，MUR,*R,MC78XX*,MC78XXBT,MC79XX* ATMEGA32A-AUTQFP-44ATMEGA2560-16AUTQFP-100AT91SAM9260B-CUBGAAT91RM9200-CJ-002BGAAT45DB161D-MUQFNAT45DB161D-SUSOP-8AT45DB041D-SUSOP-8AT45DB642D-CNUBGAAT24C02C-SSHM-TSOP-8AT24C16BN-SH-BSOP-8AT24C128C-SSHM-TSOP-8AT24C102*W-SH-TSOP-8等等。详细请询问本公司。 诚信让我们走的更远，质量得以生存，以服务*客户！不**是二*管*！ 原装正品 *无铅 *供应 大量现货 欢迎来电在线咨询 经销代理全系列贴片二*管产品贴片SMA整流二*管-M1 M4 M7贴片SMA肖特基二*管-SS12 SS14 SS16 SS110贴片SMA肖特基二*管-SS22 SS24 SS26 SS210贴片SMA快恢复二*管-RS1A RS1G RS1J RS1M RS2M贴片SMA肖特基二*管-SS34 SS36 SS54 SS56贴片SMA*二*管-US1A US1J US1M US2J US2M贴片*快速二*管-*1J *1M *2J *2M贴片*抑制保护*雷二*管SMAJ5.0A/CA-SMAJ180A/CAS*J5.0A/CA-S*J400A/CASMCJ5.0A/CA-SMCJ400A/CA贴片稳压二*管系列ZMM55C5V1 ZM4733A BZT52C9V1 BZX84*V3 BZT52H5V1 MMSZ5V1LT1G M*Z5V6LT1G ☆☆☆☆☆ 在线网络联系方式－－－－－在线ＭＳＮ：商务ＱＱ ： 18923786542：张生 深圳市福田区中航路新亚洲电子市场二期N3B077号 温馨提示^_^ 1.根据购买数量的不同会有不同的价格浮动,以实时销售报价为准！ 2.我司库存型号繁多无法将每一型号都发布在商铺内、如有需要欢迎来电，阿里旺旺或QQ联系！下列为比较经常用到的二*管参数 1N4001硅整流二*管50V, 1A,(Ir=5uA,Vf=1V,Ifs=50A) 1N4002硅整流二*管100V, 1A, 1N4003硅整流二*管200V, 1A, 1N4004硅整流二*管400V, 1A, 1N4005硅整流二*管600V, 1A, 1N4006硅整流二*管800V, 1A, 1N4007硅整流二*管1000V, 1A, 1N4148二*管75V, 4PF,Ir=25nA,Vf=1V, 1N5391硅整流二*管50V, 1.5A,(Ir=10uA,Vf=1.4V,Ifs=50A) 1N5392硅整流二*管100V,1.5A, 1N5393硅整流二*管200V,1.5A, 1N5394硅整流二*管300V,1.5A, 1N5395硅整流二*管400V,1.5A, 1N5396硅整流二*管500V,1.5A, 1N5397硅整流二*管600V,1.5A, 1N5398硅整流二*管800V,1.5A, 1N5399硅整流二*管1000V,1.5A, 1N5400硅整流二*管50V, 3A,(Ir=5uA,Vf=1V,Ifs=150A) 1N5401硅整流二*管100V,3A, 1N5402硅整流二*管200V,3A, 1N5403硅整流二*管300V,3A, 1N5404硅整流二*管400V,3A, 1N5405硅整流二*管500V,3A, 1N5406硅整流二*管600V,3A, 1N5407硅整流二*管800V,3A, 1N5408硅整流二*管1000V,3A, 二级管相关**语: [3] 1.Freewheel diode续流二*管2.Esaki diode隧道二*管；江崎二*管3.PIN diode PIN型二*管4.Schottky diode肖特基二*管5.Schottky barrier double rectifier diode萧特基势垒双整流二*管6.Zener diode齐纳二*管7.backward diode逆向二*管8.avalanche photo diode (APD)雪崩光电二*管9.blocking diode阻塞二*管10.capacitor, diode二*管电容器11.clamp diode钳位二*管12.common-cathode double diode共阴*双二*管13.crystal diode晶体二*管14.diode-transistor logic (DTL)二*管晶体管逻辑15.diode, varicap变容二*管16.diode, tunnel隧道二*管17.diode, transient suppression瞬变抑制二*管18.diode, resistor-capacitor (RCD)电阻器电容器二*管19.diode, rectifier整流二*管20.diode, parasitic寄生二*管 交易说明：1、本店*宝贝*支持（支付宝、银行转账、现金）交易；2、如需开票则加税金。质保说明:1、如按单核对不*，请收货后24小时内与本公司提出，否则视同接受本单所载事项；（收货时间以快递官方网站数据为准）2、如对货品质量有疑问，请在收货日起三天内，以书面的形式反馈给本公司，否则视为验收合格；3、对于焊过、剪脚、上锡、上机、写入程序、客户操作失误或其它原因人为损坏的芯片不能退换！注意：芯片测试，是要芯片测试*的测试仪器来测的，所以不存在焊过、上机..........但是实际上购买少量芯片的客户，不可能用*的测试仪器来测，*直接方法就是焊上、装上、上机来测试这也没什么不妥。如有质量问题已经上机用来测试的几个芯片不能退换，其它没有动过的是可以退换的！买家切记拿到货后抽几个来测一下,质量没问题就用,不行就和卖家联系。不要*焊上直接上机用，发现质量有问题，那*损失只能买家自己承担了！温馨提示:电子元件是*型的产品，技*含量较高，由于本身可能存在着多种品牌，后辍与封装，所以可能导致参数与性能的差异，有不慎，很有可能导致元件购买错误(此种失误，非质量问题*)，为了更好的解决您的问题，请您在购买我们元件前，将您所需产品的品牌、封装、脚位及后缀告诉我们，以便我们能准确*的发货！邮费说明:运费按照货物重量计算---不同省份不同地区均不同价 ---按快递公司提供运费计算为标准收取申通（圆通）快递： *广东省内统一收取*重10元，续重1-2元，单位统一以公斤来算； *福建省,浙江省,江苏省统一收取*重10元，续重4-6元，单位统一以公斤来算； *除以上四个省份,其他部分省份均按*重12元收取，续重需联系店主按实际重量计算索取； **省份 如:黑龙江,新疆,内蒙古等，均收取*重15-18元，续重需联系店主按实际重量计算索取。顺丰快递：*广东省内统一收取*重12元，续重4-6元，单位统一以公斤来算；*广东省外统一收取*重22元，续重8-14元，单位统一以公斤来算。
